SFECIFICATION 4forming part of Letters Patent No. 313,986, dated March 17, 1885.

Application filed July 9, 18M. (No mv del.)

To all whom it may concern;

Be it known that I, FREDEICH BURCK- HARDT, of St. Charles, in the county of St. Charles, in the State of Missouri, have in-- vented a certain new and useful Improvement in Car-Floors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is aside elevation. Fig. 2 is atop view with part of the flooring removed. Fig. 3 is a bottom view. Fig. 4 is an enlarged transverse section taken on line 4 4, Fig. 2; and Figs. 5 and 6 are still'further enlarged detail views illustrating the manner of securing the ioorng to the sills and the ends of the sills to their. end pieces.

My invention relates to an improved floor or bottom for railway-cars; and it consists in features of -novelty hereinafter fully described, and pointed out in the claim.

Referring to the drawings, A represents the body of a railway-car.

B represents the sills, which are made of `I or channel iron, supported by end strips, C,

to Which-they are made fast by angle-irons D and bolts or rivets I. (See Fig. 6.) On top of each sill is secured a strip of Wood, J, by means of bolts or rivets L. (See Fig. 5.) .Secured to the strips J by screws or nails N are the boards O, that forrn the fioor of the car. A car-bottom thus formed is strong, durable, and cheap, and the .iron sills can frequently be procured where wooden ones cannot, owing to the scarcity of timber in some sections of the country. By putting strips of Wood on the metal sills the boards O can be fastened down and taken up in the usual way. The sills may be supported between their ends by crosspieces P, held up by brace-rods T.

I claim as my invention- A car-floor consisting of iron sills, end strips, angle-irons, and bolts or rivets by which the sills are secured to the end strips, strips of wood bolted to the tops of the sills, and board secured to the strips of Wood. f
